Abstract: A probe structure includes a sleeve, a needle shaft and an elastic member. The needle shaft is accommodated in the sleeve and includes a first groove for accommodating the elastic member. The probe structure further includes a conductive component installed at the bottom of the sleeve and having an end connected into the first groove, and a second groove, so that the elastic member is situated in the first and second grooves. When the needle shaft is pressed and moved, the inner wall of the second groove is contacted with an outer sidewall of the conductive component to define a second conductive channel. With the two conductive channels, the effects of maintaining stable current transmission efficiency, reducing poor contact or disconnection, and providing good structural stability are achieved.
